Abstract
1361708 Sodium percarbonate agglomerates FMC CORP 8 Nov 1972 [9 Nov 1971] 51581/72 Heading C1A Particles of Na 2 CO 3 .3/2H 2 O 2 are subjected to rotary agitation in a rotating disc or drum, contacted with aq. sodium silicate solution while in motion, allowed to agglomerate in continued motion and dried at 20-80‹ C. such that dry agglomerated particles having a bulk density of 0À4-0À9 g.cm.<SP>-3</SP>. and containing sodium silicate to provide 1-5% by weight of SiO 2 . A specified agitator is a Dravo-Lurgi Disc. The aq. sodium silicate solution may be sprayed on to the particles. The feed is preferably <50 U.S. mesh and the product is preferably 16-40 U.S. mesh. The aq. solution may have a sodium silicate concentration providing 5-20% SiO 2 and the SiO 2 : Na 2 O weight ratio may be 1 : 1 to 3 : 1. The drying of the agglomerated particles may be done in a fluidized bed.
